Just wondering if running Quelea on arm64 is possible ? installed ubuntu mate for pi4 and if Quelea would run and could be used at least as a backup if main pc crashed ---

Afraid this isn’t an area we’ve looked at - it may be possible but you’d probably have to compile it yourself, so wouldn’t be straightforward. My bigger worry though would be the Pi’s processing power - it may not be enough to sensibly run Quelea even if it could launch. If you choose to experiment please let us know - I’d be interested in the results! ---

Berry ,Thanks for the quick reply. It was more curiosity than anything else. The pi 4 actually should be ok as far as processing power. The one I have is a 4 core arm processor at 1.5 gigs and 8 gig ram. We have been using a dual core 2 thread with 4 gig ram with no problem . The pi 4 also has dual hdmi and 4k capabilities. Hope someone with more code knowledge than me will give a try. ---

I actually made an attempt at running Quelea on Raspberry Pi 3 Model B a couple of years ago and managed to get it up and running. My plan was to connect the Pi to the projector, set it up to be used on a single monitor and then remote control everything. However, the Pi 3 was too slow in the end to run smoothly. As I was poking around I took notes of what I did to get it to run, to eventually write a guide on how to set it up if anybody else was interested of a similar solution. I gave up the idea when I realized that the Pi 3 wasn’t powerful enough, but I figured I could post my notes here if parts of it could be helpful for someone looking at this post. I did have to make some changes to the code back then, not sure if there still would be the same issues today. If I understand my notes correctly, the only thing I had to remove was the code for creating the QR code. After that I built an installer and was able to install it using the instructions below. # (Unfinished) Instructions for installing a headless version of Quelea on Raspberry Pi 3 > [Using a Raspberry Pi to deploy Oracle Java FX Applications](https://www.oracle.com/webfolder/technetwork/tutorials/obe/java/RaspberryPiFX/raspberryfx.html) > [JavaFXPorts](http://docs.gluonhq.com/javafxports/#_embedded) ```auto Install OS (Ubuntu Mate is used here, but other Debian-based alternatives should also work) Download JDK 8 for ARM and unpack Download Gluon SDK https://gluonhq.com/download/javafx-embedded-sdk/ Move: armv6hf-sdk/rt/lib/ext/jfxrt.jar -> jre/lib/ext/ armv6hf-sdk/rt/lib/arm/* -> jre/lib/arm/ armv6hf-sdk/rt/lib/javafx.platform.properties -> jre/lib/ armv6hf-sdk/rt/lib/javafx.properties -> jre/lib/ armv6hf-sdk/rt/lib/jfxswt.jar -> jre/lib/ Set default Java or use path to directory sudo update-alternatives --install /usr/bin/java java '/usr/lib/jvm/jdk1.8.0_191/bin/java' 1 sudo update-alternatives --set '/usr/lib/jvm/jdk1.8.0_191/bin/java' Recommended: Setup SSH (for force closing) Optional: Setup VNC (to remote control with more ease) Increace VRAM to 128 sudo raspi-config 5 Advanced Options A3 Memory Split 128 Optional: Change resolution Install custom version of Quelea Edit preferences, e.g. use.remote.control=true single.monitor.warning=false remote.control.port=1112 mob.lyrics.port=1111 use.mob.lyrics=true remote.control.password=quelea projector.screen=0 // NB: If you use --headless=true later on when starting Quelea, there is no need to set projector.screen to 0 here Make archive of database you want to use Transfer database scp '/home/USER/.quelea/database_new.tar.gz' pi@192.168.0.4:/home/USER/.quelea/ Extract database Optional: Transfer extra Bibles scp '/home/USER/.quelea/bibles/b00.xml' pi@192.168.0.4:/home/USER/.quelea/bibles/ Make auto-starter Option 1: Create sh cd /usr/local/Quelea java -Xms400m -Dfile.encoding=UTF-8 -Dprism.ordsm.order=sw -Djavafx.platform=eglfb -jar Quelea.jar --headless=true Make sh runable sudo chmod +x SH-FILE Option 2: If you only will start Quelea with the autostarter, use the following line directly the starter instead cd /usr/local/Quelea | java -Xms400m -Dfile.encoding=UTF-8 -Dprism.ordsm.order=sw -Djavafx.platform=eglfb -jar Quelea.jar --headless=true Make starter through GUI Point to SH-FILE (/bin/sh /usr/local/Quelea/quelea.sh) or add the line in option 2 If needed for any changes: Force close: pidof java sudo kill PID Edit preferences to disable projection window: sudo nano /home/USERNAME/.quelea/quelea.preferences projector.screen=-1 Ctrl + o Return Ctrl + x To run from SSH, first write: export DISPLAY=:0 Close projection screen: (Alt + tab to find the right window) Alt + F4 ``` ---

Have you taken another stab at it with pi5 ?
